Abstract
Pipe network and floss coexisting type plastic cushion comprises plastic flosses which are randomly arranged and have connecting points, in which there is a pipe network. The technical steps are: sending raw materials into an extruder to heat and plasticize to form a fusant shape; extruding out via a rotating type forming machine head; plastic threads extruded from a discharge hole of a fixing model downwards running to the random flosses via a forming roller, and forming a connecting point at the mutual connecting point; plastic threads extruded from the peripheral groove of a rotating model in the inner side of the fixing model forming the pipe network shape, having a cavity in the pipe network shape; cooling and typing the extruded formed plastic cushion, whose middle has the pipe network distribution and the periphery has the flosses; drawing out the formed plastic cushion to a cooling machine, and according to the specification to cut. The rotating type forming machine head structure is to mount a rotating model and a processing groove on the fixing model. The rotating model is connected with a rotating mechanism. This technology and the cushion for machine head have proper integral density, proper thread-line connecting point, high firmness degree, and do not need the spraying glue enhancement, without pollution. And this invention can be equipped with the temperature adjusting component.
Description
Technical field
The present invention relates to employed rotary former in a kind of pipe network and sleave coexistence formula plastic cushion and production technology and the production technology.
Background technology
Traditional elasticity of plastics mattress pad is made up of the plastics sleave of lack of alignment, production process is raw material to be sent into the extruder plasticizing of heating form the melt shape, be piled into unordered adhesion shape silk pad through the fixing downward extruded material of porous spinneret again, then through typing, cooling, cutting, spray complicated procedures of forming such as glue increases the jail, adheres to base wad, oven dry and make goods.Too much coincidence when causing unordered plastic strip adhesion because of its process characteristic, and fail fully effectively to utilize to cause the quality of unit volume heavier in the space; Because of its plastic strip is to connect after the template stickingly, influence is in conjunction with fastness again.Though strengthen through spray glue, improved performance, whole fastness still is not ideal enough, and spray glue also cannot say for sure to demonstrate,prove uniformity; Simultaneously, produced a lot of harmful volatile matters, environment has been caused to a certain degree pollution through this process again because of must flash baking behind the spray glue.The bulk strength of product is poor, and the inboard of pad does not have the space to pack into to heat or cooling-part, and use is restricted.
Summary of the invention
The purpose of this invention is to provide that a kind of global density is moderate, the strand tie point is moderate, need not to spray that glue strengthens, firmly degree height, pollution-free, inboard have and strengthen pipe network, at the inner chamber of pipe network pipe network and sleave coexistence formula plastic cushion and the production technology and the rotary former of temperature adjustment parts can be installed, and overcome the deficiencies in the prior art.
Pipe network of the present invention and sleave coexistence formula plastic cushion, it comprises lack of alignment and the plastics sleave 7 of tie point is arranged each other, it is characterized in that: show pipe network 6 in the plastic cushion inboard row, the periphery of described pipe network 6 is made up of the plastics sleave of band tie point, forms cavity in the inboard of pipe network 6.
Pipe network of the present invention and sleave coexistence formula plastic cushion, wherein said pipe network 6 is for several and line up one or more layers side by side, the orientation of pipe network 6 and the vertical consistency of plastic cushion.
The production technology of pipe network of the present invention and sleave coexistence formula plastic cushion is characterized in that: comprise the steps:
A, raw material is sent into the plasticizing of heating in the extruder form the melt shape;
B, extrude by rotary former, the plastics silk that the fixed die discharge opening on fixed die is extruded operation downwards forms unordered sleave shape through setting roll again, and at the place of being in contact with one another formation tie point; Be positioned at the plastics silk of the rotation mould perimeter trench place of fixed die inboard extruding and form the pipe network shape, side forms cavity within it;
C, have pipe network to distribute to the centre of extruding, the in type plastic cushion that is with sleave outward carries out cooling and shaping;
D, the plastic cushion after will finalizing the design pull out cooling device, cut by specification.
Employed rotary former in the production technology of pipe network of the present invention and sleave coexistence formula plastic cushion, it comprises the mold 15 in inner logical fused materials chamber, material cavity in the mold 15 be connected mold 15 on fixed die 1 on fixed die discharge opening 2 be communicated with, it is characterized in that: be provided with the rotation nib in the inboard of fixed die 1, in rotating nib, be provided with and rotate mould 3, the periphery that rotates mould 3 is processed with groove 5, be processed with groove 4 at the periphery that rotates nib, described rotation mould 3 is a plurality of being arranged in a row or more, each rotates mould 3 and all connects the gear 14 that is positioned at the outside through rotating shaft, and the gear 14 in each rotating shaft is meshing with each other and switches through actuation mechanism.
Employed rotary former in the production technology of pipe network of the present invention and sleave coexistence formula plastic cushion, wherein said fixed die 1 top be fixedly connected sequentially backing plate 12, rebound 13, mold 15 transitional pores 16 of inner logical fused materials chamber on rebound 13 and fixed die discharge opening 2 and groove 4 and groove 5 are connected.
Pipe network of the present invention and sleave coexistence formula plastic cushion are owing to have pipe network to exist in the cushion inboard, pipe network has played the effect of a reinforcement, intensity, the non-deformability of cushion have been improved, and overall weight alleviates, materials reduce relatively, the inner chamber of pipe network can be used for installing thermoregulation part in use, as electric heating part etc.; The tie point of the plastics silk mattress pad sleave part of this explained hereafter is moderate, and global density is moderate, because pipe network tie point place is not adhesion again after extruding, so in conjunction with the fastness height, need not to spray glue and strengthen, has simplified production technology, and production process is not polluted,
